I am currently working at the Cour de Cassation where we work on various aspects of legal texts using neural models like bidirectionnal language models and transformers.
During my PhD in the S2A (Signal, Statistics and Learning) and GRETA teams of Telecom ParisTech, I worked on the detection and analysis of opinion in oral interactions. I used probabilistic graphical models for opinion mining, using hybrid techniques recognizing linguistics patterns with Machine Learning methods in order to characterize an expression of opinion. I worked under the supervision of Chloé Clavel and Slim Essid.
